After reading John Mayer's controversial recent interviews, Billy Corgan is convinced Mayer is trying to self-destruct. "He's trying to destroy his career," Corgan told Rolling Stone's Brian Hiatt in an interview outtake from RS' revealing new Corgan feature in the new issue, on sale now. "Rather than take a year off or change his musical direction... some part of it is irritating his soul to the point where he's trying to blow it up. Certainly a talented guy, but empathetically, standing on the sidelines, it's hard to watch someone literally burn their career to the ground — speaking as somebody who's done it."

Corgan also responded to Mayer's comments on their mutual friend Jessica Simpson ("sexual napalm," Mayer called her). "As far as it pertains to her. I think for any person who has celebrity to sort of drop rocks at somebody else's feet like that — there's things you should really just keep your mouths shut on. There's things that should just be left alone."
